I set these on my 35 degree wall with a combination of the HB sloper 100 and the system feet #8. This combination of holds on a 35 degree wall yields V5+. Compared to the HB 100, on a wall at this angle, the HB sloper 90 is a lot easier to hold. They are small enough that you can pinch them, too, but they still require some focus to hold on a steep angle, especially if you are standing on the system feet #8. A good medium-sized hold for the crowded spray wall.
